Jeff is interested in toning his abdomen. What muscles would you tell Jeff to exercise to accomplish his goal? What movements would best exercise these muscles?


Jeff should do exercises that flex and twist the trunk. The muscles he should target are the rectus abdominis muscles, and the external and internal oblique muscles. Sit-ups and twisting movements will stimulate these muscles. If he places a weight on his chest as he does sit-ups, it will produce faster results because the rectus abdominis muscle would be working against a greater load.

Describe the structures of the glottis

A) The glottis contains the vestibular ligaments that extend between the thyroid cartilage and the arytenoid cartilages. B) The glottis contains the large epiglottis that covers the glottis during swallowing and the thyroid cartilage which forms most of the anterior and lateral walls of the larynx. C) The glottis contains the vocal folds that contain the vocal ligaments and the rima glottidis which is the opening between the vocal folds. D) The glottis contains the superior, middle, and inferior meatuses, which swirls air in the larynx producing sound. E) The glottis contains a vestibule and a septum. As air passes through the vestibule it is split by the septum producing sound.
